Setting the Node Warning Level in Network Performance Monitor

Table of contents

Overview

A device may drop packets or fail to respond to a poll for many reasons. Should the device fail to respond, the device status is changed from Up to Warning. On the Orion Polling Settings view, you can specify the Node Warning Level, which is the length of time a device is allowed to remain in the Warning status before it is marked as Down. During the interval specified, the service performs "fast polling" (ICMP) to continually check the node status.

Note: You may see events or receive alerts for down nodes that are not actually down. This can be caused by intermittent packet loss on the network. Set the Node Warning Interval to a higher value to avoid these false notifications. For more information, see “Managing Packet Loss Reporting”.

Environment
